A toast to the venerable Remington 700 5R mil-spec

Win brass
44.3 gr varget
CCI br2
178 amax at 2.82 oal

Only 70 left loaded 😔 and I have to make a new load.
Pretty close to a load ive been using lately. How long is your barrel and what is the velocity ?

Here lately I've just been loading 45gr of varget and a 175/178 in lapua or sig hybrid cases and burning up old win LR primers. Accuracy is always right around .5 moa and velocity is between 2720 and 2740 from a 20" 9 twist lilja.

The 175 Aeromatch did real well for me last week on 3" steel out to 600 yards at my local gun club. I didn't want to like the smk knockoff but it shot really well. Going to load 20 more and push it farther this weekend against the 178 eld-m.

a quote for today's America

We are doomed, not because of bad leaders or social decay, but rather because we park on a driveway and drive on a parkway, and because we can’t even spell “phonetically” phonetically.
“Driveway” is a carryover from the time when large homes would have a “drive” that connected them to the public street or road.

“Parkways” were originally envisioned to be long, narrow parks with an associated roadway.

We “park” an automobile because in the very early days of the automobile, the only convenient place to leave an auto inattended overnight was in a park.

You are welcome.

Accessories Accuracy International AI 308 Winchester barrel

I have a 24" AI short action (AT/AX/AT-X) 308W barrel. It’s the factory AI Wintac 1-10 barrel. It has 162 rounds through it. I bought it to have a 308 barrel, but I shoot 6BRA almost exclusively in my AT-X.

Let me know if you want more info and pictures. I’m asking 650 for the barrel.

6mm PRC

Guess I'll give an update since it's been a while. It still hammers but it felt like I was getting too many flyers with the Atips resulting in overall bigger group sizes. Not sure if that's the barrel burning out or the bullets not being able to hold up to the RPMs, so I figured I'd try some Berger LRHT 109s that I was able to find and I've wanted to try them over the Atips for a while. I like the Berger consistency and thick jacket of the target line to keep the bullets together at speed (though to be fair I haven't had any issue with the Atips in that regard). I tried the same powder of n565 and got pretty much the same results as the Atips, maybe ever so slightly better groups.

Then I figured I'd try some h1000 that a buddy had laying around and that shrunk the groups by a decent amount and it also meters really well. I also like the temperature stability of the Hodgon's because I'd easily get 75fps swings from summer to winter with n565. I prefer a load that I can keep the same all throughout the year.

I ended up with 58.5grs of h1000 that sent the 109s at 3405 fps from my 26" barrel. Not bad at all. I also proofed the bullet at this speed at distance and made it to 800 yards without any jacket separations, that's with my 7.5 twist 5R Bartlein, for another data point.

Chrono data is with 20 shots

I'd still like to improve groups a bit more since we're in the off season but I'm not sure what else to try. Maybe a neck trim to get the case mouths consistent? For me, the case mouths come out kind of warped / slanted after the neck down from 6.5. Has anyone burned out a barrel on this yet? By my estimation, this barrel is at around 600 give or take, so I feel like it should still have some life left in it.

Other thing I've been considering trying is the 115 DTAC with Nosering that all the 6 UM guys on Rokslide talk about. Could potentially produce better group sizes, but David Tubb only sells them in batches of 500 and I'm not sure I want to jump into that kind of commitment without testing them first.

Oh and I also found out while sighting in for night time thermal coyote hunting that n565 in sub 30 degree weather and CCI BR2 primers cause hangfires and poor ignition. Switched to FGMM MLRPs and problem was solved. I haven't tested the BR2s with the h1000 but frankly I don't care to since I have enough FGMMs in my stock.

Here's some of those 110 Atips hammering some yotes. I love that it just absolutely anchors them even on the longer shots.
